Small flavor suggestion for /e casts that by typing /e casts [any spell you have memorized or available to cast] you will use the appropriate vfx instead of having to start to cast it and then cancel it.
I like this immensely!
Tie it to Spellcraft so for every 3 points you can do a higher spell level VFX, whether you can cast it or not.
At 27 Spellcraft you could type /e casts Weird.
